Study Finds No Link Between Marijuana Use And Lung Cancer – ScienceDaily

Posted on by

“People who smoke marijuana–even heavy, long-term marijuana users–do not appear to be at increased risk of developing lung cancer…

Marijuana smoking also did not appear to increase the risk of head and neck cancers, such as cancer of the tongue, mouth, throat, or esophagus, the study found.

The findings were a surprise to the researchers. “We expected that we would find that a history of heavy marijuana use–more than 500-1,000 uses–would increase the risk of cancer from several years to decades after exposure to marijuana,” said the senior researcher, Donald Tashkin, M.D., Professor of Medicine at the David Geffen School of Medicine at UCLA in Los Angeles.”

“Biological activity of cannabinoids is caused by binding to two cannabinoid receptors CB1 and CB2. Psychoactive is not only tetrahydrocannabinol (THC) but also: cannabidiol, cannabigerol or cannabichromen.

Formerly, the usefulness of hemp was assessed in the relation to temporary appeasement of the symptoms of some ailments as nausea or vomiting.

Present discoveries indicates that cannabis-based drugs has shown ability to alleviate of autoimmunological disorders such as: Multiple sclerosis (MS), Rheumatoid arthritis (RA) or inflammatory bowel disease.

Another studies indicates that cannabinoids play role in treatment of neurological disorders like Alzheimer disease or Amyotrophic lateral sclerosis (ALS) or even can reduce spreading of tumor cells.

Cannabinoids stand out high safety profile considering acute toxicity, it is low possibility of deadly overdosing and side-effects are comprise in range of tolerated side-effects of other medications.

In some countries marinol and nabilone are used as anti vomiting and nausea drug. First cannabis-based drug containg naturally occurring cannabinoids is Sativex. Sativex is delivered in an mucosal spray for patients suffering from spasticity in MS, pain relevant with cancer and neuropathic pain of various origin.

Cannabis side-effects varies and depend from several factors like administrated dose, rout of administration and present state of mind. After sudden break from long-lasting use, withdrawal symptoms can appear, although they entirely disappear after a week or two.”

“Alcohol causes cancer, and here’s the evidence… Many of us are aware of the short-term effects of drinking too much – feeling sick, a hangover, a spot of embarrassment, a vague but hard-to-pin-down sense of guilt – but the long-term effects often slip under the radar. These include a higher risk of many cancers, heart disease, stroke and more.”   http://scienceblog.cancerresearchuk.org/2010/01/28/alcohol-and-cancer-the-evidence/

“Molecular mechanisms of alcohol-mediated carcinogenesis… Although the mechanisms for alcohol-associated carcinogenesis are not completely understood, most recent research has focused on acetaldehyde, the first and most toxic ethanol metabolite, as a cancer-causing agent. Ethanol may also stimulate carcinogenesis… Alcohol-related carcinogenesis may interact with other factors such as smoking, diet and comorbidities, and depends on genetic susceptibility.” http://www.ncbi.nlm.nih.gov/pubmed/17646865

“Liver cancer and alcohol… Based on the association of alcohol with cancer, a International Agency for Research on Cancer working group recently deemed alcoholic beverages “carcinogenic to humans,” causally related to occurrence of malignant tumors of the oral cavity, pharynx, larynx, esophagus, liver, colorectum, and female breast.”  http://www.ncbi.nlm.nih.gov/pubmed/23101985

“Alcohol consumption and the risk of breast cancer… Epidemiologic studies addressing the association of alcohol consumption with breast cancer consistently suggest a modest association and a dose-response relationship… Data from a variety of epidemiologic studies suggest that chronic alcohol consumption even in moderate amounts increases a woman’s risk for breast cancer… Epidemiologic data further suggest that consumption of larger amounts of alcohol is associated with a higher risk of breast cancer…  Avoiding overconsumption of alcohol is recommended, especially for women with known risk factors for breast cancer.”  http://www.scielosp.org/scielo.php?script=sci_arttext&pid=S0036-36342011000500012&lng=en&nrm=iso&tlng=en

“Alcohol-Attributable Cancer Deaths and Years of Potential Life Lost in the United States. Objectives: Our goal was to provide current estimates of alcohol-attributable cancer mortality and years of potential life lost (YPLL) in the United States. Results: Alcohol consumption resulted in an estimated 18,200 to 21,300 cancer deaths, or 3.2% to 3.7% of all US cancer deaths. Conclusions: Alcohol remains a major contributor to cancer mortality and YPLL. Higher consumption increases risk but there is no safe threshold for alcohol and cancer risk. Reducing alcohol consumption is an important and underemphasized cancer prevention strategy.”  http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3673233/

“Ethanol-induced mast cell-mediated inflammation leads to increased susceptibility of intestinal tumorigenesis in the APC Δ468 min mouse model of colon cancer… Chronic and frequent alcohol (ethanol [EtOH]) intake has been associated with an increased incidence of several types of cancers including breast, mouth, throat, esophageal, stomach, and colorectal (CRC). The underlying mechanism of this deleterious carcinogenic effect of alcohol has not been clearly established… Our data show that chronic alcohol intake promotes: (i) intestinal tumorigenesis and tumor invasion in genetically susceptible mice; (ii) increases in polyp-associated mast cells; and (iii) mast cell-mediated tumor migration in vitro. Both our in vivo and in vitro studies suggest that mast cell-mediated inflammation could be 1 mechanism by which alcohol promotes carcinogenesis.”  http://www.ncbi.nlm.nih.gov/pubmed/23320800

Amphiregulin is a factor for resistance of glioma cells to cannabinoid-induced apoptosis.

Posted on by

“Gliomas, one of the most malignant forms of cancer, exhibit high resistance to conventional therapies. Identification of the molecular mechanisms responsible for this resistance is therefore of great interest to improve the efficacy of the treatments against these tumors. Delta9-Tetrahydrocannabinol (THC), the major active ingredient of marijuana, and other cannabinoids inhibit tumor growth in animal models of cancer, including glioma, an effect that relies, at least in part, on the ability of these compounds to induce apoptosis of tumor cells.

…we identified the epidermal growth factor receptor ligand amphiregulin as a candidate factor to mediate the resistance of glioma cells to cannabinoid treatment… in vivo silencing of amphiregulin rendered the resistant tumors xenografts sensitive to cannabinoid antitumoral action.

Amphiregulin expression was associated with increased extracellular signal-regulated kinase (ERK) activation, which mediated the resistance to THC by blunting the expression of p8 and TRB3-two genes involved in cannabinoid-induced apoptosis of glioma cells.

 Our findings therefore identify Amphirregulin as a factor for resistance of glioma cells to THC-induced apoptosis and contribute to unraveling the molecular bases underlying the emerging notion that targeted inhibition of the EGFR pathway can improve the efficacy of antitumoral therapies.”

“Δ9-Tetrahydrocannabinol (THC), the major active ingredient of marijuana, and other cannabinoids inhibit tumor growth in animal models of cancer, including glioma, an effect that relies, at least in part, on the stimulation of autophagy-mediated apoptosis in tumor cells. 

…Altogether, our findings identify Mdk as a pivotal factor involved in the resistance of glioma cells to THC pro-autophagic and antitumoral action, and suggest that selective targeting of the Mdk/ALK axis could help to improve the efficacy of antitumoral therapies for gliomas.”
